Convertible notes | First Issuance On November 13, 2018, the Company issued convertible promissory notes (the “November 2018 Notes”), together with related warrants to acquire an additional 50% of the shares issued upon the conversion of the November 2018 Notes (the “November 2018 Warrants”), for an aggregate purchase price of $2,450,000 (the “November 2018 Private Placement”). On January 3, 2019, the Company issued additional convertible promissory notes from this issuance (the “November 2018 Notes”), together with related warrants to acquire an additional 50% of the shares issued upon the conversion of the November 2018 Notes (the “November 2018 Warrants”), for an aggregate purchase price of $200,000 (the “November 2018 Private Placement”). The November 2018 Notes carry an interest rate of 8.00% per annum and mature on May 13, 2019 and July 3, 2019 (the “November 2018 Maturity Date”), respectively, upon which date the outstanding principal amount of the November 2018 Notes and all accrued and unpaid interest shall automatically convert into shares of the common stock of the Company at the price per share equal to the lesser of (i) $13.00 and (ii) the average closing price of the Company’s Common Stock on the Nasdaq stock market for the ten days preceding the day to the conversion of the November 2018 Notes (the “November 2018 Conversion Price”). The total number of shares of Common Stock to be issued upon automatic conversion shall equal the outstanding principal amount of the November 2018 Notes and all accrued and unpaid interest on the November 2018 Notes, divided by the November 2018 Conversion Price. The November 2018 Warrants are exercisable for an additional fifty percent (50%) of the shares of Common Stock issued upon the conversion of the November 2018 Notes (the “November 2018 Warrant Shares”). The per share purchase price (the “November 2018 Exercise Price”) for each of the November 2018 Warrant Shares purchasable under the November 2018 Warrants shall be equal to the lesser of (i) $15.00 and (ii) the average closing price of the Company’s Common Stock on the Nasdaq stock market for the ten days preceding the day of the conversion of the November 2018 Notes. The November 2018 Warrants will be issued upon conversion of the November 2018 Notes. The November 2018 Warrants expire eighteen (18) months from the date of the conversion of the November 2018 Notes (the “November 2018 Expiration Date”). The Investors may exercise the November 2018 Warrants at any time prior to the November 2018 Expiration Date. Due to the variable conversion price, the November 2018 Notes contain characteristics of a variable share-forward sales contracts (“VSF”) under the guidance of ASC 480-10. Management has determined that for the purpose of the accounting for the November 2018 Notes, it is more likely than not that the November 2018 Conversion Price will be below $13.00, resulting in the issuance of a variable number of shares, the November 2018 Notes are classified as a liability, and accounted for at amortized cost. Due to the variable number of warrants to be issued and the variable strike price of the November 2018 Warrants, these do not meet the “fixed-for-fixed” criteria under ASC 815-40. Accordingly, the November 2018 Warrants are classified as a derivative liability, initially measured at fair value and subsequently revalued at fair value through the income statement. The fair value was calculated using a Monte Carlo simulation. The transaction costs related to this issuance were split pro-rata between the November 2018 Notes and the November 2018 Warrants. The portion relating to the November 2018 Notes were deferred and are being amortized over the life of the convertible notes. The portion relating to the November 2018 Warrants was immediately expensed. The aggregate value of the November 2018 Notes and November 2018 Warrants as shown on the consolidated balance sheet are broken down as follows: May 31, 2019 February 28, 2019 Issue Date November 2018 Convertible Notes – Liability - $ 2,495,636 $ 2,495,636 Accrued interest – Liability - 60,793 - Deferred financing costs - (26,557 ) (63,738 ) Total - 2,529,872 2,431,898 November 2018 Warrants – Liability - $ 219,531 $ 154,364 On April 5, 2019, the Company and the Investors that purchased the "November 2018 Notes from the Company pursuant to the Note and Warrant Purchase Agreement dated as of November 13, 2018 or January 3, 2019, executed an Amendment, Surrender and Conversion Agreement (“Conversion Agreement”) whereby the parties agreed to convert the November 2018 Notes, and all accrued and unpaid interest, into shares of the common stock of the Company at a newly agreed conversion price per share equal to $8.55 (the “New Conversion Price”), replacing the previous formula which converted the November 2018 Notes and accrued and unpaid interest into shares of the common stock of the Company at the price per share equal to the lesser of (i) $13.00 and (ii) the average closing price of the Company’s Common Stock on the Nasdaq stock market for the ten days preceding the day to the conversion of the November 2018 Notes. The Conversion Agreement stipulates that the interest on the November 2018 Notes would be paid up to and including April 3, 2019. Pursuant to the 2018 Note Purchase Agreement, the Investors also received related warrants to acquire an additional 50% of the shares issued upon the conversion of the November 2018 Notes. As part of the Conversion Agreement, the exercise price of the November 2018 Warrants will also be the New Conversion Price, replacing the previous formula which established the conversion price for the November 2018 Warrants as the lesser of (i) $15.00 and (ii) the average closing price of the Company’s Common Stock on the Nasdaq stock market for the ten days preceding the day of the conversion of the November 2018 Notes.

At the January 2020 Maturity Date, the outstanding principal amount of the January 2019 Notes shall automatically convert into shares of the common stock of the Company at the price per share equal to $8.10 (the “January 2020 Conversion Price”). The January 2020 Conversion Price may be adjusted in the event that the Company issues common shares in a private sale or offering at a lower price per share than $8.10 within 180 days of the closing date. The lower price would become the new conversion price of the January 2019 Notes, which would impact the number of shares that would be issued. The total number of shares of Common Stock to be issued upon automatic conversion shall equal the outstanding principal amount of the January 2019 Notes divided by the January 2020 Conversion Price. With respect to accrued and unpaid interest at the January 2020 Maturity Date, the Investors have the option of receiving cash or common stock of the Company at that date. Upon the January 2020 Maturity Date, where the Investor elect’s payment of accrued and unpaid interest on the January 2019 Notes in common stock, the price per share shall be equal to the trading price of the common stock at the close of the market on the date immediately preceding the January 2020 Maturity Date.

A beneficial conversion feature (“BCF”) of a convertible note is normally characterized as the convertible portion feature that provides a rate of conversion that is below market value or “in-the-money” when issued. The BCF related to the issuance of the January 2019 Notes was recorded at the issuance date. The BCF was measured using the intrinsic value method and is shown as a discount to the carrying amount of the convertible note and is credited to additional paid-in capital.
